All group licenses now use the new TAH license. In many cases, the new TAH covers everything which a user had under the group license, and more. If you were a member of the group license, and you now try to run Matlab, you will be warned that the license number has changed. You are then prompted to deactivate the old license and activate the new one.
If you are unsure about what to do in this case, you may, temporarily, simply cancel the warning and Matlab will run normally. However, this will only be a viable option for a limited time, so at some point you will need to go through the
simple one-time process of deactivating and reactivating described below.
To reactivate a copy of standalone Matlab which only needs the 16 TAH toolboxes
Launch Matlab. Under Help->Licensing click on the Activate Software option. You will be directed to the Mathworks website, where you can login with your email address as the username. The password is set by you, and can be sent to your email address if you forgot it. It is NOT your standard GT username or password, but rather a separate account with the Mathworks. Once you are logged into the Mathworks, select the TAH (which is license number 621625) when the
licenses are displayed. You should have permission to activate the software right there. If not, please contact either
firstname.lastname@example.org or email@example.com.
Note: This may be a good time for those who have paid for maintenance to upgrade to vesion 2010a. One big advantage to doing that is to be able to use the Parallel Computing Toolbox which is available through the TAH.
Here is a manual procedure in case the process above doesn’t work. In the instructions below, $MATLABROOT is the MATLAB installation folder.
- Click the Start Menu, go to “All Programs”, then “MATLAB”.
- Go to the folder for the release of MATLAB you wish to activate (e.g. R2010a)
- Click the option to “Activate MATLAB”
You can also launch the activation client directly by running activate_matlab.exe from $MATLABROOTbinwin32 or
For Unix/Linux/Mac OS X:
Run the script activate_matlab.sh in the $MATLABROOT/bin folder. To launch this script:
- Open a Terminal window (On Mac OS X, go to Applications > Utilities > Terminal)
- In the Terminal window, run the following commands:
cd $MATLABROOT/bin ./activate_matlab
For MATLAB 7.8 (R2008b) and later on Mac OS X:
In this case, you can also launch the activation client from Finder:
- Locate the MATLAB folder in your Applications folder (e.g. MATLAB_R2008b.app).
- Open the MATLAB folder by hitting CTRL+Click (or right-click) and select “Show Package Contents”.
- Double-click on “Activate” in the MATLAB folder to start the activation client.
To activate a standalone Matlab which needs additional toolboxes not included in the 16 TAH toolboxes
If you have a copy of Matlab which was covered by the old campus group license, and also needs toolboxes other than the 16 TAH tooboxes, you may need to perform an extra step, to activate each license separately. First activate Matlab using the TAH as described above (with TAH license 621625). Then, now that you have a valid, activated Matlab license, go back and activate the additional toolboxes which should appear as “child licenses” of the TAH under group license number 271272. If you need help with this, you can either send a message to firstname.lastname@example.org or contact the mathworks directly.
